A trio of order announcements by Airbus on Tuesday highlighted a state visit to Vietnam by French President François Hollande this week. The contracts, consisting of a firm order from Vietjet for 20 A321s, a firm order from Jetstar Pacific for 10 A320s and a memorandum of understanding from Vietnam Airlines covering 10 A350-900s, carry potential value of some $6.5 billion at list prices.

Vietnam Airlines last year became the first airline in East Asia and the second in the world to operate the A350 XWB. The carrier already now flies four of the aircraft in revenue service and expects delivery of another 10 on firm order. The additional 10 aircraft covered by the September 6 agreement will allow Vietnam Airlines to operate nonstop to the U.S. West Coast, carrying 305 passengers in a three-class premium layout, said Airbus.

The Vietjet order covers 10 A321neos and 10 current-generation A321s. The airline plans to use the airplanes as a growth platform for its domestic and regional network. Vietjet and Airbus also sealed an agreement for the manufacturer to provide training services for flight crew and maintenance personnel at the airline’s new facility in Ho Chi Minh City. Plans call for the Vietjet facility to provide the same Airbus-overseen courses as those offered at the airframer’s own training centers.

Finally, the order from Jetstar Pacific—a joint venture between 70-percent owner Vietnam Airlines and Qantasmarks the first direct purchase by the airline from Airbus. The aircraft will join an existing fleet of 12 leased A320-family aircraft flying on domestic and regional routes. Jetstar Pacific operates a total of 33 domestic and international routes as part of the larger Jetstar Group network, which includes Jetstar Airways (Australia), Jetstar Japan (Japan) and Jetstar Asia (Singapore).
